BUTTON.

SPECIFICATION forming part of Letters Patent No. 417,940, dated December 24, 1889.

Application filed'Maroh 19,1889. erial No. 303,913- (No model.)

To aZZ whom, it may concern:

Be it known that I, CHARLES RADCLIFFE, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Buttons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in buttons known as self-fastening buttons, which improvement is illustrated in an application contemporaneous herewith, in which the main parts of the button are the same, but the means for looking or securing the shoe to the hub or back-plate differ in construction and constitute the principal features of novelty of the invention.

The present invention is shown in the accompanying sheet of drawings, in which similar letters of reference are employed to indicate corresponding parts.

Figure 1 represents a vertical section of the improved button. Fig. 2 is a plan View of the locking parts, and Fig. 3is perspective views of a perforated spring-plate. Fig. 4 is a plan View of a modified form of springplate arranged within the hub or back-plate of the button; and Fig. 5 is a section through line 00, Fig. 4. Fig. 6 is a vertical section of a button, showing still another form of springplate. Fig. '7 is a blank from which said spring-plate is formed, and Fig. 8 is a crossseetion of the plate. Fig. 9 represents a form of button in which the spring-plate is arranged above the barbed head of the post on y the shoe. Fig. 10 is a blank of said springplate shown in Fig. 9, and Fig. 11 is a sec tion of still another form of spring-plate.

In the several views described in the above, A represents the button, a the face-plate, which is secured to the hub or back-plate b by means of the overlapping edges to in the ordinary manner. The hub or back-plate b is provided in the bottom thereof with a perforation b, above which is arranged the spring plate (1, preferably U-shaped, as is illustrated more especially in Figs. 1 and 3, and which is provided with a slot or perforation d, corresponding in shape to the slot or perforation b in the hub or back-plate. As has been stated, the spring-plate d is bent U- shaped, having arms or tongues 61 which are arranged diametrically across the opening I) in the hub or back-plate, and with which prongs f on the head f of the post f engage, and thereby firmly secure the top part of the button to the shoe e when arranged or attached on the material. It is evident that the post may be struck up directly on the shoe (2, or on a separate plate f, which maybe secured to the shoe in any well-known manner. To hold the spring-plate cl in position when arranged across the perforation in the hub or back-plate, I may provide the spring-plate with a number of metal strips or tongues d which extend out from the plate and by means of which the spring-plate is firmly secured between the overlapping edges of the hub or back plate.

Instead of forming the spring-plate as illustrated in Figs. 1 and 3, I may use a metal I blank, which is circular and perforated in the center to allow the insertion of the head on the post therethrough, and on each side of said perforation the lips or tongues cl are turned up, as indicated in Figs. 6 and 8. When used in this manner, the spring-plate is placed in the bottom of the hub or back-plate, similar to the arrangement of the plate shown in Figs. 1 and 2, et seq, and as described; but the parts may be reversed, as will be clearly understood from Figs. 9 and 11,inwhichthis arrangement of the spring-plate within the hub or back-plate is illustrated. When used in this manner, the spring-plate 61, provided with the arms or tongues (1 is reversed, the arms on said plate extending downward and being provided with perforations d d therein to receive the prongs f f on the post f, as will be clearly understood from Fig. 9.

In Fig. 11 is shown still another form of construction of the spring-plate, in which the tongues or arms d are turned up, as at (1 01 in order that the prongs f on the head f of the post f may engage with the edges of said arlns'in a manner similar to that shown in Fig. 1.

Having thus described my invention, what I claim is 1. A button consisting of a slotted hub or back-plate, a faceplate secured thereto, a U- shaped spring-plate arranged Within said hub or back-plate and having a centrally-arranged slot therein, arms formed integrally on said spring-plate, said arms extending up therefrom in a plane at right angles to the longest diameter of the slot in said spring-plate, and a shoe having a flat and pointed post thereon adapted to be forced through the material and to enter said slots in the back-plate and the spring-plate, said post having means thereon adapted to engage with and extend at right angles across and catch over the upwardly-extending arms, substantially as and for the purposes set forth.

2. The herein-describedbutton, consisting of a face-plate a, a hub or back-plate'f I), having a perforation b centrally arranged in the recessed portion of the back-plate, a springplate (Z, having a perforation d therein, and arms (1 formed integrally on said plate, and a shoe 6, having aplate f and apost f thereon provided with prongs f adapted to engage With said arms (1 on the plate d, Within the back-plate of the button, substantially as and for the purposes set forth.

In testimony that I claim the invention set forth above I have hereunto set my hand this 15th day of March, 1889.

CHARLES RADCLIFFE.
